紅銅
紅銅即純銅,又名紫銅,具有很好的導(dǎo)電性和導(dǎo)熱性,塑性極好,易于熱壓和冷壓力加工,大量用于制造電線、電纜、電刷、電火花專用電蝕銅等要求導(dǎo)電性良好的產(chǎn)品。 即赤銅。由硫化物或氧化物銅礦石冶煉得來的純銅,可用以鑄錢及制作器物。 明 宋應(yīng)星 《天工開物?銅》:“凡銅供世用,出山與出爐,止有赤銅。以爐甘石或倭鉛參和,轉(zhuǎn)色為黃銅;以砒霜等藥制煉為白銅;礬、硝等藥制煉為青銅;廣錫參和為響銅;倭鉛和寫﹝瀉﹞為鑄銅。初質(zhì)則一味紅銅而已。” 郭沫若 《中國(guó)史稿》*一編第三章第二節(jié):“他們冶煉的紅銅成分很純,除天然的微量(0.1-0.2%)雜質(zhì)外,沒有人工加入錫或鉛使成合金。紅銅的硬度雖較差,但直接經(jīng)過捶打就能制成各種工具和裝飾品。” 特性:高純度,組織細(xì)密,含氧量極低。無氣孔、沙眼、疏松,導(dǎo)電性能極佳,電蝕出的模具表面精度高,經(jīng)熱處理工藝,電極無方向性,適合精打,細(xì)打,具有良好的熱電道性、加工性、延展性、防蝕性及耐候性等。 用途:可應(yīng)用于電器、蒸溜建筑及化學(xué)工業(yè),尤其端子印刷電器路板,電線遮蔽用銅帶、氣墊,匯流排端子。電磁開關(guān)、筆筒、屋根板等。 紅銅的密度:8.96g/(cm) 紅銅的比重:8.89g/(mm) Cu≥99.95% O<003 電導(dǎo)率≥57ms/m 硬度≥85.2HV[1]
